Abstract (en)

An exhaust system (10) for an internal combustion engine (11), which is provided with a feeding pipe (5) of fresh air to an intake manifold (3) and with a turbocharger (16) arranged along the feeding pipe (5); the exhaust system (10) displays: an emission pipe (11) for releasing the exhaust gases produced by the internal combustion engine (1) into the atmosphere; at least one gas treatment device (12), which is arranged along the emission pipe (11) and consists of an oxidising catalyser (13) and an anti-particulate filter (14); and a recirculation circuit (26), which displays a recirculation pipe (27) which is regulated by a recirculation valve (28) and connects the emission pipe (11) downstream of the treatment device (12) to the intake pipe (5) upstream of a compressor (18) of the turbocharger (16) to introduce into the intake pipe (5) a certain amount of exhaust gases present in the emission pipe (11); along the recirculation pipe (27) a filter (38) consisting of a metallic mesh (39) arranged to close the recirculation pipe (27) is arranged.
